Linings
British Gypsum systems provide high quality internal linings. They cater for a variety of wall and roof constructions, including metal frame and traditional masonry. Linings can be fully or partially independent of the structure, or can simply be bonded or plastered directly to a wall surface. These products are used in all types of buildings and are equally suited to both new-build and refurbishment work.
Each system section takes you through the process of selecting an appropriate lining to achieve a high performing, quality finish:

Thermal improvement
British Gypsum has a wide range of Gyproc ThermaLine laminate plasterboards to achieve thermal performance for all projects; from basic regulatory requirements to the most stringent, high performance levels. Buildings that have high levels of thermal insulation cost less to run, reduce CO2 emissions and improve occupier comfort.
Acoustic improvement
British Gypsum has a wide range of wall lining systems that offer a number of acoustic performances. Improvements in the acoustic environment of a building can lead to a number of occupant benefits, including enhanced student learning, improved patient recovery, optimised employee productivity and harmonious family living.
Enhancing the built environment
British Gypsum offers a range of systems to deliver rooms and buildings that offer superior levels of living comfort and sustainability.
It is well recognised in the construction industry that there is an issue with buildings not performing as intended when it comes to energy efficiency, often referred to as the 'Performance Gap'. In order to minimise this risk there are two key areas of system design and installation to which particular attention should be paid; airtightness and thermal bridging.
To maximise the performance achieved on site, consider the following good practice specification guidance:
— In order to reduce heat loss via convection currents, it is important to seal the perimeter of the insulating element. To achieve best performance, a continuous fillet / ribbon of Gyproc DriWall Adhesive or Gyproc Sealant should be applied to the wall perimeter and around all services and openings as board fixing proceeds, as per individual system design guidance
— Air leakage through blockwork can be significant, particularly through incomplete mortar joints. Air passing through the wall will take heat energy with it, reducing the thermal efficiency of the wall. A continuous 6mm coat of Gyproc SoundCoat, applied to the face of the masonry prior to the installation of DriLyner systems, will seal hidden air paths often found in mortar joints between blocks or bricks. For improved acoustic performance, the Gyproc SoundCoat should not be trowelled smooth
— Walls must be weathertight and free from dampness before any DriLyner or plaster system can be installed
— It is important to achieve as consistent a level of insulation performance as possible across a building element. Areas with less insulation, known as cold bridges, will be prone to attracting condensation and, as a result could promote mould growth. Consideration should be given to minimising the occurrence of cold bridges, for example by applying thermal laminates to lintels and window reveals

GypLyner iwl
GypLyner iwl independent wall lining is a lightweight, non-loadbearing system, which is built independently of the external wall construction. GypLyner iwl is particularly suitable for buildings where fixing into the background is difficult or not possible. The lining provides fire resistance and acoustic upgrades to structural steel sections clad with lightweight metal sheeting, and can also be used in within new or existing masonry walls to increase sound insulation and meet stringent thermal performance requirements.
Key benefits
— Totally independent from wall with fixings to floor and soffit only, particularly suitable for basements with waterproof tanking
— Any surface irregularities within the external wall construction are completely removed through the totally independent framework
— Services are easily incorporated within the framework with no limitation to the cavity size that can be created
— A wide range of U-values can be achieved to suit project requirements through our extensive selection of Gyproc ThermaLine laminate types and thicknesses
— Minimal thermal bridging due to the use of a totally independent framework
— Provides a high-performance option to achieve enhanced acoustic performance and fire protection to steel, in one lining solution

1 The fire resistances apply to external walls, whose construction incorporates structural steel sections with a profiled steel cladding, when the inside of the wall
is exposed to fire.2 For improved durability and impact resistance, the outer layer of board can be replaced with a layer of Gyproc DuraLine.3 Where the external wall is more than 1m from the boundary, Building Regulations allow relaxation of the provision for insulation to 15 minutes in certain
circumstances.4 The figures quoted relate to the complete wall structure including the external cladding. The lining also offers fire protection to steel columns from the lining
side, subject to A/V (Hp/A) factor. Refer to table 3.
The fire resistance and sound insulation performances are for imperforate partitions, walls and ceilings incorporating boards with all joints taped and
filled, or skimmed according to British Gypsum’s recommendations. The quoted performance (from the underside to the ceiling plenum only) are achieved only
if British Gypsum and Saint-Gobain Isover components are used throughout, and the company’s fixing recommendations are strictly observed. Any variation in
the specification should be checked with British Gypsum.

Building design
Whilst GypLyner iwl lining systems are non-loadbearing, they are
able to provide resistance to levels of horizontal non-uniformly
distributed loads.
Refer to C02. S01. P26 – Robustness.
Planning - key factors
GypLyner iwl comprises of Gypframe ‘I’ Studs installed at 600mm
centres within Gypframe Floor & Ceiling Channels to receive board
to one side. The position of services should be pre-determined
and their installation planned into the frame erection stage. It is
important that all parts of the lining system, including the thermal
insulation, should remain independent of the external walling. The
lining is erected with the external walling in place and the windows
and doors fixed.
Extended heights
Where the wall height exceeds the available length of the
Gypframe ‘I’ Stud, sections of stud can be spliced together to the
required length using 600mm lengths of the appropriate floor and
ceiling channel, fixed with four British Gypsum Wafer Head Drywall
Screws in each flange to each side.
Refer to construction detail 2.
Where greater heights than listed in table 1a and 1b are required, it
may be possible to brace the lining back to the structure. Note that
the system is non-loadbearing and should not be used to provide
lateral restraint to masonry or other external wall constructions.
Junction with a suspended ceiling
Where a GypLyner iwl system is to be fixed to the framework
of a CasoLine mf ceiling, in accordance with British Gypsum’s
installation instructions, it’s permissible maximum height is
equal to that of where it is fixed direct to a structural soffit of
the same height.
In situations where a GypLyner iwl system passes through
a CasoLine mf ceiling, which is to one side of the lining and
appropriately fixed to both this lining and perimeter partitions /
walls, consideration can be given to the lateral restraint provided by
the ceiling when developing the lining specification.
The relevant maximum height is the greater of the floor to
CasoLine mf ceiling or ceiling to structural soffit height. Care should
be taken during installation of tall linings so as to not adversely
affect their performance.
Acoustic performance
GypLyner iwl can be used as an independent lining to improve the
sound insulation of new or existing masonry walls. Acoustic testing
on a basic masonry wall construction achieving Rw
45dB sound
insulation gave a 14dB improvement when the wall was lined with
GypLyner iwl. A 16dB improvement was achieved with a double
layer lining incorporating Isover insulation. Refer to table 4. Careful
detailing is required at junctions with sound insulating partitions in
order to maintain acoustic performance.
Refer to construction detail 6.
Cavity fire barriers
Cavity fire barriers should be included where necessary. If both
sides of the cavity are formed by non-combustible or Class 0
materials, barriers are necessary only every 20m. The nature of the
barrier and its fixing should not detract from the general
performance of the wall.
Fixing floor and ceiling channels
Gypframe Floor & Ceiling Channels must be securely fixed with a
row of fixings at 600mm maximum centres. For 94mm and 148mm
channels, two rows of staggered fixings are required, each row at
600mm centres and each fixing 25mm in from the flange. If the
floor is uneven, a 38mm thick timber sole plate equal to the width
of the channel should be used.
If the concrete or screeded floor is new, consideration should be
given to the installation of a damp-proof membrane between the
floor surface and the channel or sole plate.
GypLyner iwl design
Important information
Walls must be free from damp before the GypLyner iwl system can be installed.
Handy hint
A continuous coat of 6mm Gyproc Soundcoat Plus, applied to the face of the masonry prior to the installation of DriLyner systems, will seal hidden air paths often found in mortar joints between blocks or bricks. For improved acoustic performance, the Gyproc Soundcoat Plus should not be trowelled smooth.
Important information
The inclusion of control joints should be considered.
Refer to C02. S01. P30 – Robustness, and construction details 7-8 within this section.

Deflection heads
The system can accommodate deflection at the head with suitable
detailing incorporating Gypframe Deep Flange or Extra Deep Flange
Floor & Ceiling Channels.
Refer to C02. S01. P10 and C07. S05. P09 – construction detail 4.
Damp or rain penetration
In refurbishment projects, where damp or rain penetration may
exist, normal corrective measures, such as a new damp course,
tanking, or external wall coating, must be taken prior to the
installation of the dry internal lining. The cavity between the
external wall and the lining system could be drained and ventilated
to the outside.
Thermal performance
Uncontrolled air movement through the drylining cavity can result
in excessive heat loss from the building. This can be reduced in
practice if the abutting elements and the background are well
fitted, and junctions are sealed. The designer should also specify
a method of restricting air movement around the perimeter of
suspended timber floors, such as the provision of a flexible seal
between the floor and walls.
Condensation and water vapour resistance
Gyproc WallBoard duplex and some Gyproc ThermaLine laminates
offer significant resistance to water vapour transmission.
The application of two coats of Gyproc Drywall Sealer to
Gyproc WallBoard, Gyproc Moisture Resistant or
Gyproc ThermaLine basic after installation and jointing provides a
water vapour resistance of at least 15MNs/g.
The use of Gyproc WallBoard duplex or Gyproc ThermaLine laminates
with integral vapour control, or supplemented with a vapour
control layer treatment such as two coats of Gyproc Drywall Sealer,
significantly reduces the risk of interstitial condensation.
It is important, particularly in new buildings, that external walls
are properly dried out before a vapour control layer is provided,
otherwise moisture may be trapped, impairing the performance of
the construction.
Solid masonry wall - internal insulation
We reference to the use of Hygrothermal properties of buildings
components within modelling software, and in compliance with BE
EN 5250 (August 2016), we now recommend specialist guidance
to be obtained prior to commencing the installation of internal
insulation to solid masonry walls in order to determine the effects
of condensation and moisture within the building fabric. This
area of expertise is documented within BS 5250 ‘Code of practice
for the control of condensation of building components and
building elements - Assessment of moisture transfer by numerical
simulation.’
GypLyner iwl design (continued)
Insulation
Isover Steel Frame Infill Batts are inserted to a friction-fit within the
stud cavity. The slabs are self-supporting, receiving internal support
from the stud flanges, except where 50mm insulation is fitted
into Gypframe 92 I 90 or 146 I 80 ‘I’ Studs. In this case, a 150mm x
50mm strip of Isover Steel Frame Infill Batts is inserted to retain the
slab. With Gypframe 146 I 80 ‘I’ Stud, two strips of insulation should
be inserted to retain the slab.
Services
The stud cut-outs can be used for services provided that the
Isover insulation remains in place. The positioning of stud cut-outs
is shown in construction detail 1.
Surface mounted services should be located against the
plasterboard lining, and fixed through the lining to the stud
framework. Any interruptions in the lining integrity will downgrade
its performance. The installation of electrical services should be
carried out in accordance with BS 7671.
Fixtures
Lightweight fixtures can be made directly to the partition linings.
Medium weight fixtures can be made to Gypframe 99 FC 50 Fixing

GypLyner iwl installation overview
Additional information
For full installation details, refer to the British Gypsum Site Book, available to download from british-gypsum.com
This is intended to be a basic description of how the system is built.
For detailed installation guidance refer to the British Gypsum Site Book.
Gypframe Floor & Ceiling Channels are
suitably fixed to the floor and soffit.
Gypframe ‘C’ Studs are suitably fixed to
openings and abutments.
Gypframe ‘I’ Studs are friction-fitted
vertically at the required centres within the
channel sections to form the framework.
Additional framing is installed as required
to support heavy fixtures.
The perimeter of each frame is then sealed
with Gyproc Sealant.
If specified, Isover insulation is fitted
between studs. Electrical and other services
are normally installed at the frame erection
stage. Horizontal runs are fixed to the
background or can be routed through
cut-outs in the studs.
Gypframe 99 FC 50 Fixing Channel can be
installed between studs to support recessed
switch boxes / socket outlets.
Boards are screw-fixed to framing members
to form the lining. Horizontal board joints
should be backed with Gypframe GFS1
Fixing Strap or Gypframe GFT1 Fixing ‘T’.
